Title: X-ray preionized laser unit
Inventor: SUZUKI SETSUO
IPC: H01S3/03
Filed: 1990-03-05
Abstract: PURPOSE:To enhance reliability of an X-ray transmitting metal film electrode and to lengthen service life by arranging an X-ray generating target, independently from one of main discharge electrodes or the X-ray transmitting metal film electrode, in a low pressure chamber. CONSTITUTION:Ions, produced through discharge in the proximity of an ionization wire anode 9, are attracted to a grid electrode 11 and impinge against an acceleration cathode 13 thus producing secondary electrons. The secondary electrons are then accelerated between the acceleration cathode 13 and the grid electrode 11 and impinge against the inclined face of an X-ray generating target 7 thus generating X-ray. Thus generated X-ray then passes through an X-ray transmitting metal film electrode 1 and irradiates the interior of a main discharge chamber 15, and a laser medium is excited by a high voltage applied between a main discharge electrode 17 and the X-ray transmitting metal film electrode 1 thus causing oscillation. When the X-ray generating target 7 is arranged independently from one main discharge electrode or the X-ray transmitting metal film electrode 1, in a low pressure chamber 3 both thermal load and mechanical load of the X-ray transmitting metal film electrode 1 are relieved, resulting in the improvement of reliability and lengthening of service life.

Abstract: PURPOSE:To obtain a static shattering agent easily filling in a hole, with excellent reaction efficiency of CaO and exhibiting high power by incorporating a highly water-absorptive substance to a powdery or granular substance wherein CaO is a main component and preparing a hollow cylindrical molding by compression molding. CONSTITUTION:A static shattering agent, obtd. by compression-molding a powdery or a granular substance wherein CaO is a main component, is a hollow cylindrical molding prepd. by impregnating it with a highly water-absorptive substance (e.g. a polyacrylic acid salt). This molding has a diameter which is small enough to be inserted into a hole and the diameter is pref. about 0.95-0.85 of the diameter of the hole. It is pref. that the diameter 1 of the hollow part is about 0.2-0.3 of that of the molding 2. Thus it can be easily filled in a hole as compared with a powdery or granular form and the retention of water is easier than a cylindrical molding, so that the reaction efficiency of CaO is excellent and a high power is exhibited. In addition, since the outlet for steam exists, spouting hardly occurs and water can be fed afterwards, so that the reaction efficiency of CaO can be furthermore improved and a higher power can be exhibited.
